History & Science behind Whole-Body Vibration

چکیده
As there is minimal gravitational force in space, muscles and bones are not loaded as they normally are on earth. Cosmonauts (and astronauts) in space lose their muscular strength very quickly (muscle atrophy), which is why they are not able to easily walk when they come back to earth. The decrease of bone density increases the risk of bone fractures, so it's not safe to stay in space for extended periods. As a result they were forced to return to earth rather quickly.
